ARTHUR MOGONAGLE, OF EAST ORANGE, NEW JERSEY.

STEAM-HEATING SYSTEM AND APPARATUS.

SPECIFICATION forming part of Letters Patent N 0. 788,933, dated May 2, 1905.

Application filed November 15, 1904. Serial No. 232,779.

To all whom, it may concern:

Be it known that I, ARTHUR MoGoNAeLE, a citizen of the United States of America. and a resident of East Orange, county of Essex, State of New Jersey, have invented certain new and useful Improvements in Steam-Heating Systems and Apparatus, of which the following is a specification, reference being had to the accompanying drawings, forming a part thereof.

My invention relates to improvements in steam-heating systems and apparatus, and particularly to the means for employing steam from condensing-engines.

My invention consists in inserting a loaded valve or other resisting means in the returnpipe from the steam-engine and in connecting the inlet and discharge pipes of a steam-heating apparatus with the said steam-engine return upon opposite sides of the said loaded valve, so that the same constitutes a by-pass around the valve.

The object of my invention is to economically employ the eXhaust-steam from condensing-engines while providing automatic means for carrying the steam direct to the condenser when the steam is turned off from the heating-pipes or from any other cause the resistance in the heating-pipes becomes too great.

I will now proceed to describe a steam-heating system and apparatus embodying my invention and will then point out the novel features in claims.

The drawing herewith illustratesdiagrammatically an apparatus embodying my invention.

A conventional type ot'engine 1 is i-llustrated,havinga steam return-pipe or discharge 2. This pipe connects with a condenser 3, said condenser connected with exhausting apparatus 4 by a pipe 5. A loaded valve 6 is arranged in the return-pipe 2, said valve provided with means for varying the load in an adjusting-screw 7 and spring 8.

9 designates a radiator representing a portion of a steam-heating system, of which 10 is the supply-pipe and 11 the discharge. The supply and discharge pipes 10 and 11 are connected with the engine-return 2 upon opposite sides of the loaded valve 6, the supply 10 being connected upon the side next the engine, while the discharge 11 is connected on the side next the condenser.

The operation is as follows: The valve 6 is adjusted for the required load-as, for example, to ten pounds or, say, about twenty inches on the mercury scale. The steam-heating system when in full operation offers a resistance equal to, say, eighteen inches on the mercury scale. The exhausting apparatus 4 will then draw the steam from the return 2 through the inlet 10, radiators 9, discharge 11, and condenser 3. Should the steam-heating system be cut off, the steam will be drawn directly through the engine-return 2, past the loaded valve 6, and through the condenser in the ordinary manner. Should a portion of theheating system be shutoff, a portion of the steam may pass around through that portion of the heating system still open, a portion of the steam passing through the loaded valve. The loaded valve in the position in which it is arranged will form an automatic means for permitting such quantity 01 the steam as is required for steam-heating purposes to pass through the steam-heating system, while the remainder will pass direct to the condenser. All the steam will finally pass to' the condenser, because the steam-heating system is merely arranged in a loop or bypass around the valve, the discharge 11 thereof discharging into the condenser. means the steam from condensing-engines may be employed for steam-heating purposes in an economical and etficient manner without interfering with the normal operation of the engine. It will of course be obvious that other forms of means for resisting passage of steam below a predetermined pressure may be employed instead of the loaded valve.

What 1 claim is- 1. In a steam-heating system and apparatus, the combination with the return-pipe of a steam-engine, acondenser to which the returnpipe is connected, and an exhausting apparatus for the condenser, of automatic pressureactuated resisting means arranged in the return pipe between the condenser and the steam-engine, said means arranged to prevent the passage of steam below a predetermined By this.

pressure therethrough, and steam heating means arranged as a loy-pass around said resisting means.

2. In a steam-heating system and apparatus, the combination With the return-pipe of a steam-engine, and an exhausting. apparatus connected thereto, of an automatic loaded valve arranged in said return-pipe, and steamheating apparatus arranged with its inlet and exhaust connected with the said engine steam- I return upon opposite sides respectively of the said loaded valve. v

In Witness whereof I have hereunto set my hand this 11th day of November, 1904:.
